Don’t break the chain.
Pick one thing to do every day. Each day you do it, you forge a link. Miss a day and the chain snaps back to zero.
Free with one chain.
No account, no ads.


Hold to forge today’s link.
Press and hold for a second. The link ratchets shut, the chain clanks, and your iPhone answers with haptics tuned to feel like real steel. One tap could be an accident; a hold is a promise.
It warns you before midnight.
Not done by 21:00? Chainy sends one time-sensitive alert, a live countdown sits on your Lock Screen, and the chain starts to strain. One reminder in the morning, one alert at night. Nothing else.


Miss a day, it snaps.
That is the whole point. Something real is on the line, so you show up. With Pro, you get freezes: patch one missed day with an ice link and the chain lives on.

The chain gets harder to break.
Every milestone forges your links from a harder material, climbing the hardness scale from steel to diamond. A year in, nothing on Earth is harder than your chain.


Every day, at a glance.
Each week is a row of links. Solid for done, ice for a freeze, red where it broke. Your best run stays on record, even after a snap.
Your chains stay yours.
Stored on your iPhone. There is no Chainy server holding your data.
